Examples of java.nio.LongBuffer

• java.nio.LongBuffer
  A long buffer.

  This class defines four categories of operations upon long buffers:

  • Absolute and relative {@link #get() get} and{@link #put(long) put} methods that read and writesingle longs;

  • Relative {@link #get(long[]) bulk get}methods that transfer contiguous sequences of longs from this buffer into an array; and

  • Relative {@link #put(long[]) bulk put}methods that transfer contiguous sequences of longs from a long array or some other long buffer into this buffer; and

  • Methods for {@link #compact compacting}, {@link #duplicate duplicating}, and {@link #slice slicing} a long buffer.

  Long buffers can be created either by {@link #allocate allocation}, which allocates space for the buffer's content, by {@link #wrap(long[]) wrapping} an existinglong array into a buffer, or by creating a view of an existing byte buffer.

  Like a byte buffer, a long buffer is either direct or non-direct. A long buffer created via the wrap methods of this class will be non-direct. A long buffer created as a view of a byte buffer will be direct if, and only if, the byte buffer itself is direct. Whether or not a long buffer is direct may be determined by invoking the {@link #isDirect isDirect} method.

  Methods in this class that do not otherwise have a value to return are specified to return the buffer upon which they are invoked. This allows method invocations to be chained. @author Mark Reinhold @author JSR-51 Expert Group @version 1.62, 06/07/10 @since 1.4
